In this paper, based on Darcy equations that govern the lubricant in porous layers, and the modified Reynolds equation in the framework of a short bearing solve the problem of unsteady motion of a viscous incompressible lubricant in the bearing clearance double-layer porous. Here we consider the case when the permeability in porous layers in the axial direction is changed by the normal law, and the combined feed lubrication is performed simultaneously in the axial and perpendicular to the bearing axis directions. As a result, the pressure field found in porous layers and in the lubricating layer and analytical dependences for the efforts of the oil film. Compiled by the equation of motion tongue and solved the problem of the stability of the unsteady motion of a pin bearing, found that in the case of a combined bearing lubrication working more steadily compared with the cases or axial directions perpendicular to the axis lubrication. The results obtained can be offered for the development of cylindrical dampers with double-layer porous collar, effectively attenuating transmitted force imbalance in the combined feed lubrication.
